Comments Information

    • Function

    • Lanthionine-containing peptide antibiotic (lantibiotic) active on Gram-positive bacteria. The bactericidal activity of lantibiotics is based on depolarization of energized bacterial cytoplasmic membranes, initiated by the formation of aqueous transmembrane pores.

    • PTM

    • There are one didehydrobutyrine (T14), two lanthionines (S3-C7; S16-C21) and one Beta-methyllanthionine (T8-C11) and one S-(2-aminovinyl)-D-cysteine (S19-C22).
